yikes..

if you're going to try to get it out with brute force, do this:

- unbolt the entire LCA, and bring the shock and LCA out as one piece. the other two bolts on the LCA don't seize like that shock bolt does. any decent impact wrench should get them out.
- find yourself a strong drill bit that can handle drilling forged steel. it should be approx. the width of the bolt, and it should be a strong drill.
- mount the LCA down in a vice or something so that will it will not move.
- start drilling the bolt out, from the snapped end.. if you have a grinder, it's not a bad idea to grind off the welded nut, so that you can drill from either end of the bolt. this will also help in case you're worried about going off track and drilling into the bushing.

it will take some effort and a little time, but if you have a steady arm, you'll save yourself any extra work of replacing the bushing, and your method of attack focuses on just one point.

this is what i had to do for both rear LCAs and the only extra thing i had to pay for was new bolts.
